A slider moves over a curved guide whose shape in the vertical plane is given by x = βηβη , y = βcos(hηβcos(hη). Starting from x = 0, the speed is observed to vary as υυ = υ0υ0 (1-ks), where ' s' is the distance traveled and 'k' is a constant. Derive expressions for the velocity and acceleration of the slider as functions of ' x '.

Explanation & Answer

Attached.

The travelled distance is s
2-D KINEMATICS
The formula for displacement is s=ut+(1/2)at2s=ut+(1/2)at2
The formula for velocity is v=u+atv=u+at
These are the two equations of kinematics that can be used to solve the
question.
Velocity is the differentiation of displacement with respect to time and
acceleration is the differentiation of velocity with respect to time.

The shape in plane is given by,
x=βη.............................(1)x=βÎ...
